Good afternoon, been looking at the Bluetti AC200P, but I also want to know how a home-built system would work and compare, and using the 640Wh "Milk Crate" build as a basis, I've been looking at a 24V system:
MPPT Controller: https://www.amazon.com/dp/B01MSYGZGI (40A Renogy)
Battery w/ BMS: https://www.amazon.com/dp/B08P6LP1J9 (24v 100Ah Ampere Time - I'm aware this is overpriced, just an example unit)
Inverter: https://www.amazon.com/dp/B07GDH711G (2000w 24v Giandel)
AC Charger: https://www.amazon.com/dp/B08GFQZFC1 (10a, Adjustable voltage, DOKO)
In addition, I'd have a buck converter set to 10A@13.8V for powering 12v DC things, and the same USB power output mentioned in the video, since it accepts 24v input. I'd also have 2 fuse blocks, one for 12v the other for 24v. The buck converter would be upgraded as needed for more 12v output.
What I want to know is if there's any glaring issues, i.e. is there anything that will prevent this system from working, and if these specs are true about the resulting build:
Inputs:
AC Input - 240W
PV Input - 1000W
Outputs:
AC 2000W, 2400W Peak (100A * 24V)
DC 10A@13.8v, whatever I fuse it at for 24V, up to 100A, Multiple USB ports per the spec of the USB charger
Storage:
2560Wh nominal, realistic usage in practice closer to 2300Wh
PV Inputs:
From what I understand, this system should be able to charge at roughly 1kW, however overpaneling it seems to be a bit tricky. Assuming I'm using this for the panel:
I believe that I can do a 5x4 configuration for a 2000W theoretical max, however the charging circuitry would only output 1000W to the batteries. Would 5 in series, paralleled 4 times be a valid configuration?
Misc:
There's no reason why I wouldn't be able to charge and run in this configuration, right? Does the choice of a battery with a built-in BMS limit my future expandability? How difficult would it be to add more of these batteries in **parallel** in future. Edit: meant parallel not series.
